This invention relates in general to handling devices and in particular to buckets or grapples adapted for handling manure or like material.

Theinvention comprehends the provision of a device of the above character embodying means for opening and closing certain coacting sections, said sections being operatively connected to material-handling means in the form of tines.

Another feature of the invention resides in 1 the provision of p a' plurality of tines connected to said cdacting sections in a manner to permit their placement, adjustment, and removal with the least possible loss of time.

. A further object is to provide means'in the form of shoes which may be attached to the points of said tines and thus permit the functioning of the device in a manner similar to the clean-up bucket. Y

The invention is further featured by an .improved construction wherein the work of loosening the material is facilitated and made more rapid in the transferring of said mate- 2 rial according to the attendant circumstances.

Further objects and advantages of my invention will become apparent as the description proceeds, and in order that the same may be better understood, reference is had to the so accompan ing drawings forming a part of this speci cation.

In said drawings:

Figure 1 is a side elevation of the device embodying my invention, an open position thereofbeing indicated'in dot-and-dash lines.

Fi ure 2 is an end view of the same to clear y illustrate the connection between certain co-acting sections and tines, the shoemember hereinbeforc referred to being shown secured. to the tines.

Figure 3 is a view like unto Figure 1, but depicting the sections in substantially full' open position. v

F igure 4 is a perspective detail of the shoemem er p Figure 5 is a sectional detail taken substantially on the line 5-5 of Figure 6, to show the connection between one of the tines and said shoe-member. 1 50 Figure 6 is another sectional detail taken the upper ends thereof being secured to a on the line 6-6 of Figure 5, further illustrating: the connection shown in said Figure 5. igure 7 somewhat diagrammatically illustrates an operation of the device, the co-actin sections in this figure having approache one another to a point to cause certain tines to be firmly embedded in the material-ban;

died and ready for transfer to another point.

Figure 8 illustrates the device equipped with shoe-members and performing the operation of cleaning the deck of a scow or the like, of the material remaining thereon after the operation of the tines.

The essential parts of my device comprise the sections 10 and 11 pivotally connected to-' gether by-the shaft 12, and on inspection of Figure 2 it will beobserved that said sections are each provided with a air"of .spaced lugs 13 and 14 at their outer en s, for pivotally receiving the ends of the connecting bars 15 and 16, there being two bars for each section, the upper ends of said bars bein inclined and connected to a common pivot 1 Disposed between the upper ends of said I bars 16 is a filler block 18, to which is connected the supporting line 19 (see Fig. 3), said block having a side extension which is bifurcated to pivotally receive an idler 20 whichengagesthe operating rope 21, entering through the guide thimble 22. From this point said operating rope 21 continues downwardly, where it is connected to the circum ferentially grooved power wheel 23, mounted on said power shaft 12. I In this particular instance I prefer to op-' eratively connect said pivot 17 and said power wheel 23 through the medium of a pair of flexible members 24, in the form of a chain,-

suspending rod 25, connected to said pivot- 17, its other extremity being connected to the 1 hub 26 of said power wheel. Each of said chains consists of a duplex section 24 and a single sectionv24, so constructed that when the power wheel has made one complete rotation, as in the closing of the device, the said sections will each wrap completely around the hub without such sections overlapping, as will be well understood by those As clearly shown in Figure 2 I have provided a rope guard having spider-like arms 27, their inner ends being secured to a web or'tion 28 mounted on said power shaft 12. lach of the arm portions is provided with a shoe 29, which extends part of the way into the circumferential groove arranged in said wheel 23 for a urpose well understood, and which is also. ully shown anddescribed in m said patent already referred to.

The essential features of the main operative portion of my device having now been described in detail, I direct particular attention to certain features of my invention associated with said sections 10 and 11. Inow refer to the tine-members, denoted generally by the numeral 30, and point out that due to the structure of said sections, which consist of solid or single-piece members, arranged as shallow scoo s with side portions, tops, and rears especially adapted to receive my tine-members, I am enabled to secure a twopoint connection between said sections and tine-members and thus am assured of a rigid and secure connection. For instance, let us consider the outer tines 31 and observe that they are arcuately disposed, having their upper endsarranged within the rear portion of the sections and bolted thereto, as shown at 32, while their extreme tips are reduced and pass through apertures in the top of said sections and are there pinned as lndicated at 33. The lower portion of said tines have their outer edges tapered gently to facilitate their insertion into a mass of material. The inner tines 34 are similarly secured to the sections, being bolted to the sides of the sections as at 35 and their upper ends also piercing the tops of the sections and pinned as shown at 36. While the inner tines naturally function as such, they really serve as stays in that they are onlly placed on both sides of the sections (see ig. 2) and when the device is in closedposition, as shown in Fig. 1, theymaterially assist in the retention of the material which might otherwise break away from the mass.

It will also be noted that, as shown in Fig. 2, the lower portion of thefiller-block 18 constitutes a sto as at 18, to limit the upward movement 0 the power wheel 23, and that this, in turn, limits the closing movement of the tines and prevents their striking when the sets come together. The illustration in Figure 7 diagrammatically shows a scow 38 carrying a quantity of material to be handled, and it will be noted that my device is now in what may be termed closed position, the tines have pierced a mass of material about to be transported to some convenient point. The value of the inner tines 34 will at once become apparent, in spite of the inherent cohesion of this t of material. 7

Obv1ousl the removal of the material as shown in lgure 7 may be continued to a polnt extremely close to the deck 39 of said scow, but in view of the somewhat sharpened points of the t nes, it is quite a arent that some means of protection shoul provided figuration of the lower portion of said'tines Y 31. The upper portion of the shoe-member is provided with a plurality of apertures 44, arranged in pairs, for the rece tion of U- bolts 45, the leg portions thereo straddling each of the outer tines 31 and firmly lockin the shoe-member over said tines througl i the medium of nuts 46, as clearly shown in Figures 5 and 6.

When these shoe-members are disposed over the points of said tines 31, a relatively wide scraping area may be covered and due to the ability of the device to assume an extremely large open position, it becomes quite apparent that a deck may be quickly and neatly scraped of its surface material.

What I claim is:

1. The combination with a grapple having pivoted scoop sections each comprising oneplece members including side, rear and top portions, of a plurality of tine-members depending from the rear portions of said sections and having their upper ends secured to 7 said rear portions and their tips attached to said top portions, and a second set of tinemembers arranged inwardly of the firstmentioned tine-members and having their upper ends secured to said side portions and their tips attached to said top portions.

7 2. In a device of the character described,

a pair of opposed pivoted one-piece scoop sections each embodying side, top and rear portions, operating mechanism for opening and closing said sections and a plurality of tine-members depending from the said rear portions and having their upper ends secured thereto and their t1 s passing through apertures formed in said top ortions.

3. In a device of the c aracter described, a pair of opposed pivoted sections, a series of arcuately disposed tine-members depending from said sections and a shoe-member conforming to the configuration of the said tine-members and adapted to envelop the depending portions thereof.

4. In a device of the character described,

a pair of opposed pivoted sections, a series of tine-members de ending from said sections and a shoe-mem er conforming to the configuration of said tine-members and adapted to envelop the depending portions thereof to convert the same into structurally unitary scraper-members.

5. In a device of the character described, a pair of opposed pivoted sections, a series of tine-members depending from said sections, a shoe-member conforming to the configuration of said tine-members and ada ted toenvelop the dependingportions thereo and means for locking said shoe-member over said tines to convert the same into structurally unitary scraper-members.
